Frequently asked questions
What is the difference between AD8541ARTZ-REEL7 and AD8541ARTZ-R2?
Both parts are the same AD8541 single operational amplifier in a SOT-23-5 (RT) package. The difference is the packaging format: AD8541ARTZ-REEL7 is supplied on a 7-inch tape-and-reel (typically 3,000 units per reel), while AD8541ARTZ-R2 is supplied on a smaller tape-and-reel (typically 250 units per reel). The electrical and package specifications are identical.
Are AD8541ARTZ-REEL7 and AD8541ARTZ-R2 electrically interchangeable?
Yes. Both order codes refer to the same AD8541 die in the same SOT-23-5 package, so the electrical parameters (supply voltage range, quiescent current, bandwidth, offset voltage, etc.) are identical. The only difference is reel quantity and packaging format.
What is the supply voltage range of the AD8541?
The AD8541 operates from a single supply of 2.7 V to 5.5 V (or dual supplies within that total range), making it suitable for low-voltage battery-powered and portable applications.
What are the key AC specifications of the AD8541?
The AD8541 has a unity-gain bandwidth of 1 MHz and a slew rate of 0.92 V/µs, with a typical quiescent supply current of 45 µA per amplifier. These characteristics suit low-power signal conditioning and sensor interface designs.
What package does the AD8541ARTZ use, and is it RoHS compliant?
The AD8541ARTZ uses a 5-lead SOT-23 (RT) surface-mount package. The "Z" suffix in the order code denotes RoHS-compliant, lead-free construction per Analog Devices' ordering nomenclature.
Which reel size should I choose between REEL7 and R2?
Choose AD8541ARTZ-REEL7 for production volumes requiring a 7-inch reel (typically 3,000 units), and AD8541ARTZ-R2 for prototyping, sampling, or low-volume builds where a smaller reel quantity (typically 250 units) is sufficient. Confirm exact reel quantities on the manufacturer datasheet or distributor listing before ordering.
Can AD8541ARTZ-REEL7 and AD8541ARTZ-R2 be used interchangeably on the same PCB?
Yes. Because both are the same device in the same SOT-23-5 package with identical pinout and footprint, either reel option can be placed on the same PCB land pattern. Selection depends only on the required order quantity and packaging format.
